What This Code Means
Z87.732 is the ICD-10-CM diagnosis code for personal history of (corrected) persistent cloaca or cloacal malformations. A person who previously had a persistent cloaca or other cloacal malformations (where the rectum, urinary tract, and reproductive organs share a common opening) that has been surgically corrected. Z87.732 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).
Z87.732 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Cloaca-related conditions are rare; ensure documentation clearly describes the specific malformation that was corrected.
